Integration
Connect MailUp and Willo
When New Email Message in List fires in MailUp, your agent runs Add department in Willo, or List Users in Willo to Create New Email Message in MailUp. Describe the whole flow and it is built, tested on every scenario and kept running.
What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it.
Build solutions, not workarounds.

Connect your AI client
Give your AI client this address.
https://mcp.apiant.aiOne connection does both: ask your client to act in an app once, or have it build an automation that keeps running. Any client that takes a remote MCP server. Nothing to install. Create your free account, then sign in once in your browser.

Questions
MailUp and Willo, answered
What can start an automation from MailUp?
Any of MailUp's 4 triggers in the catalog, including New Email Message in List, New Group, New Recipient Subscribed and New Recipient Unsubscribed. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Willo when something happens in MailUp?
Any of Willo's 19 actions, including Create Company, Create Interview, Update interview and Update participant. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Willo to MailUp?
Yes. When something happens in Willo, your agent can act in MailUp too. This page covers both directions: Willo's triggers and MailUp's actions are listed here as well.
Do I have to build a connector for MailUp or Willo?
No. Both are in the catalog with their triggers and actions. You describe the automation; your agent builds it, tests every scenario and keeps it running.
Can my AI client use MailUp and Willo without building an automation?
Yes. With your AI client connected to APIANT, ask it to do something in either app once and it runs that action on the spot. Ask for an automation and your agent builds it, tests every scenario and keeps it running. One connection covers both.
What happens when something fails?
Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships.
Is there a free plan?
Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
